No . here are original paint hoods on 340 Demons. Body assembly manual shows the small stripe . But I have never seen one in person and I have seen many.
Most always copy the drawing of the demon stripe in this ad but it is totally wrong third picture. Just like the side stripes placed to low using the vinyl stripe under the gas cap handle. where it should be painted with the handle included. I put these original stripes on in the 70's. The stripe was all ready cut out for the fuel opening. The side stripes never went down the center body line. Look at the assembly diagram. The hood stripe in the manual does show the small stripe but I never saw an original car with it applied.
